Despite improved digital access to publications as digitized artifacts, they remain document-based and often behind paywalls, impeding open science. Researchers must push beyond the established boundary of publications as digitized documents. Open science infrastructures support them in organizing and (re-)using publications and their information so that they are Findable, Accessible, Interoperable, and Reusable (FAIR) for humans and machines in the long term. The Open Research Knowledge Graph (ORKG) is one sustainably governed infrastructure for FAIR scientific information, with successful use cases in requirements engineering (RE). The tutorial aims to familiarize the participants with open science and empower them to leverage the ORKG for FAIR scientific information. The half-day tutorial consists of three sessions: 1) A short introduction to open science and the ORKG regarding their importance, benefits, and incentives, 2) An interactive session with hands-on exercises for learning skills and practical experiences to leverage the ORKG, and 3) A feedback session for reflection. The tutorial raises awareness for open science in RE, introduces the ORKG, fosters networking, and, in the best case, establishes future collaborations. The participants become familiar with open science and the ORKG by learning skills and gaining practical experience to leverage the ORKG themselves. The transition away from digitized documents and towards FAIR scientific information is a long-term endeavor. We must gradually sensitize researchers to this transition while guiding and empowering them to leverage existing solutions as an integral part of their work. The tutorial pursues this endeavor to promote open science in RE.
